Lindsay Lohan: I Deserved Sautner's Rage

Lindsay Lohan is telling friends ... she understands why Judge Stephanie Sautner threw the book at her today -- and to prove her renewed commitment to community service, Lindsay plans to put in overtime at the morgue.

We're told Lindsay has internalized Sautner's admonitions -- and is taking the entire experience today as one big warning that she needs to get her act together, stat.

As a result, we're told Lindsay will be visiting the morgue tomorrow to get started on her community service. In fact, Lindsay says she's so serious about impressing the judge ... we're told she has promised to go to the morgue every day between now and her next hearing on November 2.
